Automatically includes a parent theme RTL stylesheet for a child theme if it doesn’t have its own <code>rtl.css</code> file.
Thanks to <a href="http://www.wp-tricks.co.il/" rel="nofollow ugc">Rami</a> for the idea.

Note: Sorry about the bad header problem. Version 1.0.1 should work much better.
If you want a different CSS file (also known as a skin) for the different sites you are working on in WordPress Multi-Site you have to make a child theme (best practice) or copy a theme and change its name, css, and whatever else you may desire to change (less than optimal solution).
But wait! There is a better solution!
You can add site specific CSS to each blog individually, instead of changing your theme or using a million child themes.
This let’s you keep all the functionality built into your favorite theme and just change the look a bit. It is a much lighter solution than creating yet another child theme? which gets tedious on multi sites.
We originally developed this because we created a child theme based on twenty-ten and then wanted to create several variations? but wordpress doesn’t let you make a child theme of a child theme. Now, we do not need to. And for just thirty nine ninty… wait… It is free? What is wrong with us?
Got comments? Wanna share this with all your multi-site friends? Cool! We do too!

Site Specific CSS

Add site specific CSS to each blog individually, instead of changing your theme or using a million child themes.
